FAN..

SPECIFICATION forming part of Letters Patent No. 708,624, dated September 9, 1902.

Application filed March 31,1902. Serial No. 100,665. (No model-l To a/ZZ whom t may concern."

Be it known that I, WALTER E. COLEMAN, a citizen of the United States, residing at Newd'orp, Richmond county, and State of New York, have invented certain new and useful Improvements in Fans, of which the follow-A ing is a specification sumcient to enable 0thers skilled in the art to which Ythe invention appertains to make and use the same.

1o My invention relates to means for controlling and directing air-currents generated Pby electric fans, and is an improvement upon the construction disclosed in my concurrent application, Serial No. 90,144; and it consists in the special construction of parts hereinafter described, and claimed specifically.

In the accompanying drawings, Figure lis a plan of my improved device. Fig. 2 is a view of the under side of the device, the base zo being shown in section in plane of line 22,

" Fig. 5. Fig. 3 is a detail view of the lower end of one of the deflectors, showing a means of adjusting the deflecting-pin. Fig. 4isa section upon plane of line 4 4, Fig. 3. Fig. 5

z 5 is a side elevation, partly broken away. Fig. 6 is a front elevation of the lower portion of the device.

In my concurrent application hereinbefore referred to I employ separate worm-gears and connections for eecting the movement of the motor upon its base and of the deflectors upon the guard-frame. g

A distinguishing feature of my present invention is that I so arrange and construct the 3 5 parts that a single worm-gear and connections are so arranged as to turn the motor on its axis and simultaneously change. the inclination of the delectors with relation to said motor. The motor is movable only in a horizontal plane, being mounted upon a vertical spindle S, supported upon ball-bearings or otherwise in the base B. A

Attached to the arms g gis the guard-frame G, in which are pivotally mounted the dei'lectors D by means of pivots d, as heretofore. F is the fan, mounted upon the motor-shaft m, the forward end of which is formed with a worm-screw m', which meshes with a wormgear n upon the upper end of the vertical 5o shaft N. The lower end of this shaft N is journaled in a cross-barg of the guard-frame G, the shaft being formed with a collar W, which rests against the upper side of said cross-bar. The eXtreme upper end of the vertical shaft N is journaled in a bracket-arm ot, 5 5 formed with a sleeve a', which fits over the end of the motor-shaft m, as in my concurrent application hereinbefore referred to. The lower extremity of the vertical shaft N is provided with a crank-arm n2, to which is 6o pivotally connected the lever-arm c, the other end of said lever-arm c being pivotally connected to the fulcrum-arm b, attached -rigidly to the base B. lThus the rotation of the worm-gear n by the worm m'on the motor- 65 shaft will cause the crank n' and lever-arm c to oscillate themotor M and its spindle S in the base B, thereby changing the general direction of the current of air induced by the rotation of the fan F. V7o

The deiiectors D are held together by links d' d', so that they will all move in unison. One of the deflectors, preferably the central one, is provided with a stem or stud cl2, the lower end of which rests in a longitudinal slot e, formed in the arm E, rigidly secured to the base B and projecting therefrom radially with relation to the vertical axis of the spindle S in the construction shown in the `drawings. While I do not limit myself` to this 8o identical construction of-parts, it is preferable to have the arm E and its slot e in aline- Vment with the center, so as to render the motion of the deflectors equal on both sides of Vtheir pivots, since it will be seen that as the crank-arm n2 and the lever b rock the motor and guard-frame G back and forth the stud d2, being held and confined within the slot e, will turn the central deliector upon its pivot d in the opposite direction, at the same time 9o by reason of the links d d' moving the other deflectors in parallel lines therewith.

It is obvious that the stud d2 can be attached tolany one of the deflectors and the arm E modified in form to meet the change, the slot c being preferably in alinement with the delector when the latter is in its central position, as shown in the drawings.

In order to vary the angle and extent of deflection of the deiiectors B', I design in some too cases to make the stud cl2 adiustable, substantially as shown in Figs. 3 and 4, in which the lower end of the deflector is formed with a horizontal slot d3, through which passes a screw-stud d4, projecting from the shank d5 of the stud d2, a washer f and thumb-screw 5 f being used to clamp the shank d5 to the lower end of the deector D. It is obvious that any other Well-known mechanical expedient may be substituted for this particular means of adjustment.

It will be seen that by these improvements I simplify and cheapen the structure of the apparatus as a whole, While attaining like results as compared with my prior structures.

What I claim as my invention, and desire to secure by Letters Patent, is-

l. The combination of the fan F, electric motor M, mounted upon the vertical spindle S, said spindle S, supported in the base B, by means which admit of its turning axially, said base B, the fulcrum-arm ZJ, rigidly secured to said base, the lever-arm c, pivotally connected to said rigid arm b, and to the crank n2, said crank n2, the vertical shaft N, the Wormwheel n, the motor-shaft m, formed With the screw-Worm m', engaging with said Wormgear n, for the purpose and substantially in the manner set forth.

2. The combination ot the fan F, electric motor M, mounted on the vertical spindle S, said spindle S, supported in the base B, by means which admit of its turning axially said base B, the arm E, rigidly secured to the base B, and formed with the longitudinal slot c, the stud d2, attached to a deector D, and resting in said slot c, the deilectors D, pivotally mounted in the guard -frame G, said guard-frame G, rigidly secured to the motor, and means for Vibrating the motor for the purpose and substantially in the manner described.

3. The combination of the fan F, electric motor M, mounted upon the Vertical spindle S, said spindle S, supported in the base B, by means Which admit of its turning axially, said base B, the arm E rigidly secured to the base B, and formed with the longitudinal slot e, the stud d2, attached to a deector D, and resting in said slot e, means for adjusting said stud cl2, horizontally upon said deector, the defiectors D, pivotally mounted in the guard-frame G, said guard-frame G, rigidly secured to the motor, and means for vibrating the motor for the purpose and substantially in the manner described.

4. The combination of the fan F, the electric motor M, mounted upon the spindle S, said spindle S, supported in the base B, by means which admit of it to turn axially, said base B, the fulcrum-arm b, rigidly secured to said base the lever-arm c, pivotally connected to said rigid arm b, and to the crank n2, said crank n2, the Vertical shaft N, the Worm-gear in, the motor-shaft m, formed With the screwworm m engaging said Worm-gear n, the arm E, rigidly secured to the base B, and formed with the longitudinal slot c, the stud d2 attached to a deflector D, and resting in said slot e, the deiiectors D, pivotally mounted in the guard-frame G, and said guard-frame G, rigidly secured to the motor, the whole arranged and operating substantially in the manner and for the purpose described.
